It covers the July 1, 2010 to September 30, 2010 timeframe and includes a descripti on of activities completed under the Phase 3 Work Plan . In addition to MOU activities, 3M is performing other non-MOU studies related to PFOA to provide data for the Alabama De partment of Environmental Management (ADEM) and/or EPA Region 4. Where relevant, non-MOU data may be incorporated in the revised Screening Level Human Exposure Assessment. This non-MOU information will also be described and provided in these quarterly status reports. Details on activities completed during this reporting period are as follows: Groundwater Technical Progress • 

## Off-site groundwater – Access agreements ha ve been finalized with some off-site landowners for the installation of mon itoring well clusters and sampling of groundwater. Arrangements are being made for access to the remaining locations under private ownership and it is anticipa ted that the remaini ng access agreements will be in place within the next several months. Installation of monitoring wells and soil sampling was initiated on Sept ember 27, 2010 at three locations where agreements have been finalized. Mon itoring wells 611R, 611L and 607L were completed within this reporting period. Inst allation of the other new off-site well clusters 606, 607 and 609 was not comple ted within this reporting period, and details on this effort will be provided in the next quarterly status report. Well installation at the remaini ng locations will be perfor med as a second mobilization after access agreements are obtained. • 

## On-site Avenue A area groundwater – Twel ve temporary wells were installed by Geoprobe ® 

## borings at locations throughout the Avenue A drainage ditch area between July 7 and 9, 2010 to obtain addi tional data for the Remedial Action Agreement Program being undertak en by 3M under ADEM’s guidance. Groundwater sampling was performed at th e 11 temporary wells with sufficient yields and at one permanent well (216R). All temporary wells were abandoned upon the conclusion of groundwater sampling. Analytical results will be provided in a subsequent quarterly status report. This is not an MOU-related activity.J:\FOLDERS.0-9\3M-DECAT\Phase 3 Work Plan\3Q10 Status Report\3Q10 Status Report_FINAL.doc 10/28/2010 

## 2-2 • 

## On-site plant area groundwater – Groundw ater sampling was performed from September 20 through 30, 2010 at 17 locations in the chemical plant area and northeast of the closed landfill at the Decat ur site as part of routine quarterly monitoring. Monitoring locations included 16 individual wells and the combined groundwater from maintenance pumping wells at the closed capped landfill prior to treatment at the on-site groundwater treatment plant. The groundwater samples were submitted to the 3M Environmen tal Laboratory for PFOA analyses and analytical results will be provided in a s ubsequent quarterly status report. Closure of eight inactive former monitoring wells associated with former National Pollutant Discharge Elimination System (NPDES) monitoring in the former sludge incorporation area (FSIA) and th e construction of five new monitoring wells was performed as part of the FSIA capping program and was not a MOUrelated activity. A description of the sampling activities is provided in the Groundwater Sampling Technical Pr ogress Report (Attachment 1). Soil and Sediment Technical Progress • Off-site soil – Sampling of surface soils from the 0 to 12-inch below ground surface (bgs) depth interval at locations within approximately 2 miles of the 3M Decatur facility was performed on June 29, 2010 and described in the June 30 Quarterly Status Report . Analyses for PFOA, tota l organic carbon (TOC) and sieve grain size have been completed and results are provided in the Soil and Sediment Sampling Technical Progress Report (Attachment 2). • Off-site sediment and soil – Sampling of sediments from 15 locations along 4 transects across the Wetla nds Edge Environmental Center (WEEC) wooded swamp and upland soils from 10 locations along the perimeter of the swamp was performed June 23 to 24, 2010 and described in the June 30 Quarterly Status Report . Analyses for TOC and sieve grain si ze have been completed and results are provided in the Soil and Sediment Sampling Technical Progress Report (Attachment 2). • On-site Avenue A area soil – Between July 7 and 9, 2010, samples of surface soil (0 to 0.5 ft) and shallow subsurface soil (0.5 to 1.0 ft) were collected by hand auger at nine locations within the Avenue A area to obtain additional data for the Remedial Action Agreement Program being undertaken by 3M under ADEM’s guidance. Soil samples were also collected from 12 temporary well borings in this area. Sampling intervals in th e borings included 0 to 0.5 ft, 0.5 to 1.0 ft, 2 to 2.5 ft and the 0.5 ft interval within the capill ary fringe of the water table. Analytical results will be provided in a subsequent quarterly status report. This was not a MOU-related activity.J:\FOLDERS.0-9\3M-DECAT\Phase 3 Work Plan\3Q10 Status Report\3Q10 Status Report_FINAL.doc 10/28/2010 

## 2-3 Vegetative Uptake Study Technical Progress • The preparation of the candi date on-site borrow area in Field 14 for soil to be used in the vegetation uptake study was de scribed in the June 30 Quarterly Status Report. An additional potential borrow source area in Field 8b was prepared on July 1, 2010 and composite samples from both areas were collected for PFOA, TOC and sieve grain size analyses. Analyti cal results for these samples have been finalized and are provided in the Vegetative Uptake Study Technical Progress Report (Attachment 3). Expanded summaries of these activities, where applicable, are included as attachments to this status report and provide additional deta ils on the work which has been completed.

## Att 1-1 GROUNDWATER SAMPLING TECHNICAL PROGRESS REPORT 3M AND DYNEON DECATUR, ALABAMA Off-Site Phase 3 Monitori ng Well Installation Access agreements have been finalized with three landowners for the installation of Phase 3 off-site monitoring well clusters and sampling of groundwater. Installation of the new monitoring wells 611R, 611L and 607L was performed between September 28 and 30, 2010 at two of the three locations where agreements have been finalized (Figure 1). Bedrock wells 611L and 607L were constructed with air rotary dril ling techniques. The initial boring was constructed with a 10-inch rotary bit to allow installation of a 6-inch casing. The boring was advanced until comp etent bedrock was encountered. The boring was continued approximately 5 feet into bedrock to confirm that bedrock was intercepted. Six-inch casing with welded s eams was installed and grouted in place using tremie pipe pumping techniques. The grout was allowed to cure for a minimum of 12 hours before drilling was continued. Bedrock drilling was conducted using a 5 3⁄4-inch air hammer bit. Drilling was continued until a water-bearing fracture was encount ered that was suitable for groundwater monitoring. Upon completion of the borehole, the hole was developed using air pressure to remove drilling debris. The casing was completed with a lockable cap, the well was left to reach equilibrium conditions, and the residuum well construction commenced. The residuum well 611R was constructed using ai r rotary drilling tec hniques. The boring was constructed using an 8-inch rotary bit. Soil sampling was performed at intervals within the boring and is described in the Soil and Sediment T echnical Progress Report (Attachment 2). Upon encountering first rock (considered to represent the top of the epikarst zone), the boring was assessed to dete rmine if adequate water was present. If it was determined that water production would not be possible, the boring was advanced into the epikarst zone until an adequate wa ter zone was encountered. At location 611R, water was encountered within the residuum and the boring was completed as a residuum well, 611R. The installation of the remaining of f-site monitoring wells at those locationsJ:\FOLDERS.0-9\3M-DECAT\Phase 3 Work Plan\3Q10 Status Report\3Q10 Status Report_FINAL.doc 10/28/2010 

## Att 1-2 with access agreements in pl ace was performed after this reporting period and will be described in the subsequent quarterly status report. On-Site Groundwater Sampling Twelve on-site temporary wells were in stalled by Geoprobe borings at locations throughout the Avenue A draina ge ditch area between July 7 and 9, 2010. These wells were installed to obtain additional data for the Remedial Action Agreement Program being undertaken by 3M under ADEM’s guidance. This activity is not part of the MOU activities. Groundwater sampling was performed at the 11 temporary wells with sufficient yields and at one permanent well (216R). Th e temporary well installed at location GP06 did not yield sufficient water for sampling. Sample descripti ons are provided in Table 1 and the locations of the temporary wells are shown in Figure 2. All temporary wells were abandoned upon the conclusion of groundwater sampling. Appropriate volumes of groundwater were placed into laboratory-prepared containers which were sealed, labeled, and placed into an ice chest along with comple ted chain-of-custody forms for shipment to the 3M Environmental Laboratory in St. Paul , MN. When completed, analytical results will be reported in a subsequent quarterly status report. Groundwater sampling was performed between September 20, 2010 and September 30, 2010 at 17 locations in the chemical plant area and northeast of the cl osed landfill at the Decatur site as part of r outine quarterly monitoring. While these wells are sampled and analyzed for VOCs, 3M has elected to obtain samples from some of these wells for PFOA analyses, in accordance with an agreement reached with EPA. Therefore, this groundwater sampling event is not part of the MOU program. Monitoring locations included 16 individual wells and the combined groundwater from maintenance pumping wells at the closed capped landfill prior to tr eatment at the on-site groundwater treatment plant. The wells sampled included 203L, 220R, 220L, 222R, 227R, 227L, 310R, RW312R, 317L. 324L. RW327R, 328R, 328L, 330R, 330L, RW331S and the combined groundwater treatment plant la ndfill wells sample GRS04. Prior to sampling, monitoring wells were de veloped following established methods for the site. Groundwater was pumped from th e wells using submer sible Grundfos pumpsJ:\FOLDERS.0-9\3M-DECAT\Phase 3 Work Plan\3Q10 Status Report\3Q10 Status Report_FINAL.doc 10/28/2010 

## Att 1-3 until a minimum of three well volumes were removed and groundwater parameters (temperature, specific conductivit y, and pH) had stabilized or the well was pumped to dryness. In this latter event, the well was considered developed and allowed to recharge for sampling. Purged water was contained and transferred to th e on-site groundwater treatment plant for treatment prior to discharge into the facility wastewater treatment plant. After development, the wells were allowed to recharge and stabilize prior to sampling. Groundwater samples for PFOA analysis were collected using disposable polyethylene bailers. Appropriate volume s of groundwater were placed into laboratory-prepared containers which were sealed, labeled, and pl aced into an ice chest along with completed chain-of-custody forms for shipment the 3M Environmental Laboratory in St. Paul, MN. When completed, analytical results will be reported in a subseque nt quarterly status report. Groundwater sampling of 24 wells in the former sludge incorporation area (FSIA) fields in late June 2010 was described in the previous quarterly status report. Data developed on groundwater elevations, contour s and PFOA concentrations will be used for evaluating the effect of the multi-layer cap system currently being installed in the FSIA and is not part of the MOU program. PFOA analyses fo r these groundwater samples have been completed, and the results are provided in Table 2 and are shown in Figure 3. The analytical data package, GLP10-01-01 Inte rim Report 07, is provided in Appendix A. Closure of eight inactive former monitoring wells associated with former NPDES monitoring in the FSIA and the construction of five new monitoring wells in this area was performed as part of the FSIA cappi ng program. Sampling of the new monitoring wells (140R, 141R, 142R, 143R and 144R) and ot her existing wells is scheduled for November 2010 and information on well constr uction and sample collection activities will be provided in the next quarterly status report.Table 1Avenue A Temporary Well DescriptionsDecatur, ALSAMPLE IDAREADATETIMEWell Depth(ft bgs)DAL-GW-GP01-0-100709Avenue A Ditch9-Jul-107:0012DAL-GW-GP02-0-100709Avenue A Ditch9-Jul-1011:1515DAL-GW-GP03-0-100709Avenue A Ditch9-Jul-1011:458DAL-GW-GP04-0-100709Avenue A Ditch9-Jul-1012:0012DAL-GW-GP05-0-100709Avenue A Ditch9-Jul-1012:1010DAL-GW-GP06-0-XXXXXXFire Test AreaDAL-GW-GP07-0-100709Fire Test Area9-Jul-1010:4523DAL-GW-GP08-0-100709SWMU 49-Jul-1011:0012DAL-GW-GP09-0-100709SWMU 49-Jul-1011:358DAL-GW-GP10-0-100709SWMU 49-Jul-1011:2516DAL-GW-GP11-0-100708SWMU 48-Jul-1016:358DAL-GW-GP12-0-100712Construction Debris Area12-Jul-1011:0022DAL-GW-216R-0-100716Avenue A Ditch16-Jul-1012:3516Notes:Due to insufficient water yield, GP06 was abandoned without sampling.GP12 was installed on July 9, 2010, but due to insufficent water yield, sampling was performed on July 12, 2010.J:\FOLDERS.0‐9\3M‐DECAT\Phase3WorkPlan\3Q10StatusReport\Attachment1\Table1(Att1)AveATempwelldescription.xls

## Att 2-1 SOIL AND SEDIMENT SAMPLING TECHNICAL PROGRESS REPORT 3M AND DYNEON DECATUR, ALABAMA Off-site Soil Sampling Sampling of surface soils within rights of way adjacent to c ounty or state roads at 10 locations within approximately 2 miles of th e 3M Decatur facility was performed on June 29, 2010 and described in the June 30, 2010 Quarterly Status Report . Analyses for PFOA, TOC and sieve grain size have been co mpleted and the results are tabulated in Tables 1, 2 and 3, respectively. Sampling loca tions and average PFOA concentrations are depicted in Figure 1. Analytical data packages are provided in Appendix A. Access agreements have been finalized with three landowners for the installation of Phase 3 off-site monitoring well cluste rs and sampling of soil and groundwater. Installation of the new m onitoring wells 611R, 611L and 607L was performed between September 28 and 30, 2010 at two of the three loca tions where agreements have been finalized. Well construction details and lo cations are provided in the Groundwater Progress Report (Attachment 1). The resi duum well 611R was cons tructed using air rotary drilling techniques. The boring was constructed using an 8-inch rotary bit. Soil was collected using split-barrel samplers at pr e-designated depths and at 5-foot intervals for analytical testing and logging purposes. Soil was coll ected from 0 to1 feet, 1 to 2 feet, 4 to 5 feet and from the water table fo r analytical testing. The soil was described and placed into laboratory-prepared containers provided by the laboratory. The soil samples were submitted to the 3M Laboratory in St. Paul, MN, for PFOA analysis and results will be provided in a fu ture quarterly status report. Off-site Sediment and Soil Sampling Sampling of sediments from 15 locations al ong four transects denoted as A through D across the WEEC wooded swam p and upland soils from 10 locations along the perimeter of the swamp was performed June 23 and 24, 2010 and described in the June 30, 2010 Quarterly Status Report . Analyses for TOC and sieve grain size have been completed andJ:\FOLDERS.0-9\3M-DECAT\Phase 3 Work Plan\3Q10 Status Report\3Q10 Status Report_DRAFT.doc 

## Att 2-2 the results are tabulated in Tables 4 and 3, respectively. Analytical data packages are provided in Appendix A. The analysis of sa mples for PFOA is proceeding and results will be provided in a future quarterly status report when finalized. On-site Avenue A Area Soil Sampling Between July 7 and 9, 2010, surface soil (0 to 0.5 ft) and shallow subsurface soil (0.5 – 1.0 ft) samples were collected by hand auger at nine locations within the Avenue A area. Soil samples were also collected from 12 temporary well borings in this area. Sampling intervals in the borings include d 0 to 0.5 ft, 0.5 to 1.0 ft, 2 to 2.5 ft and the 0.5 ft interval within the capillary fringe of the water table.

## Att 3-1 VEGETATIVE UPTAKE STUDY TECHNICAL PROGRESS REPORT 3M AND DYNEON DECATUR, ALABAMA The preparation of the candidate on-site borrow ar ea in Field 14 for soil for use in the vegetation uptake study was describe d in the June 30, 2010 Quarterly Status Report . After preparing the Field 14 borrow area for sampli ng and staging, a locatio n in Field 8b was similarly prepared in the event that the Field 14 soil PFOA concentrati ons requires augmentation to attain the target concentration range. Vegetation consisting of forbs in the surrounding area was mowed with a brush hog to a height of approxima tely 3 inches and an approxima tely 6 ft by 6 ft rectangular area centered on the Phase 2 sampling location DF8b-SS-0002 was established. Cut vegetation was removed by raking and the remaining surfa ce vegetation was cropped to near ground level with a rotary brush cutter equipped with a meta l blade and re-raked. A rotary tiller was used to thoroughly till the soil to a depth of approximately 6 inches. Root wads from the vegetation were raked from the soil at in tervals during tilling. Sampling and staging of the Field 14 and Field 8b soils were performed on July 1, 2010. The field-blended Field 14 soils were transferred from the borrow area to a staging area by a front end loader and placed on 60-mil polyethylene line r material. Individual composite samples were collected from each of 5 approximately 2 cubi c yard buckets of soil. Upon completion of sampling and soil transfer, the staged soil pile was covered with additional liner material. Field 8b soils were transferred by shovel to a lined 55 -gallon steel drum and three composite samples were collected. Upon completion of sampling and transfer, the drum was sealed and moved to the Field 14 soil staging area and placed on a pallet. Samples were shipped to the 3M Environmental Laboratory in St . Paul, Minnesota for PFOA anal yses and to the TestAmerica laboratory in Chicago, Illinois for TOC analyses. On e sample of the Field 14 soil was transferred to the TTL laboratory in Decatur, Alabam a, for sieve grain size analyses. Analyses of all parameters have been completed. PFOA analytical results are provided in Table 1 and shown in Figure 1. The TOC and sieve grain size analytical results are provided in Table 2. The PFOA analytical data package, GLP10-01- 01 Joint Interim Reports 04 and 08, and the TOC and sieve grain size data packages are pr ovided in Appendix A to Attachment 2.
